Specicaton of Letters Patent.

Patented Feb. 3, 1914.

.Ap'olication filed March. 6, 1913. Serial No. 752,327.

To all 'whom it may concern:

Be it known that I, ERNEST H.,KNU'1'Z, residing at Arcata, in the county of Hum` boldt and State of California, have invented certain new and useful Improvements in Insulators and Current-Distributers, of which the following is a specification.

My invention which is an improvement on the invention disclosed in Letters Patent #1,043,321 issued to me on November 5, 1912, has for its object to provide a modified form. of the apparatus disclosed in such patent in which the cost of manufacture has been reduced. and in which the current distributer may also be employed as an insulator .without removing it from the insulator proper.-

In its general nature the invention resides in providing the current distributor arms with eyes in which hreakable insulators proper are held and around which breakable insulators the wire to bevinsulated is passed, the breakable insulators being such that when it is desired to electrically connect the insulator with the arm, the particu lar insulator is vbroken outer removed so as to enable the metallic electrical contact bey tween the wire and arm to be effected.

1n its-more detail nature, the invention embodies those novel details of construction.` combination and arrangement of parts, all of which will be first fully described, and then be specifically pointed out in the ap pended claims, reference being had to the accompanying drawing, in which:

Figure'1 is a perspective vieu7 illustrating the invention. Fig. 2 is a detail horizontal section on the line 2 2 of Fig. 3. Fig. 3 is a vertical section andl part elevation on the line 3-3 of Fig. 2. Fig, 4 is a detail view showing the manner of securing theconducting wire electrically to an arm when the breakable insulator has ieen removed.

As in my patented construction referred to, the insulator proper 4 may be of the petticoat type having ythe usual petticoats 9 and the upwardly projecting body 5 that is externally threaded at 11 to receive the com bined insulator and distributor. The body 5 is also internally threaded 8 to lit onto the threaded end of the pin 2, and the body 5 is also provided with the dome portion 12 and the wire receiving groove 13' as in my patented construction referred to. The body 16 is covered with an insulating covering 22 Vwhich is threaded at 23 to receive the threads 11. In' my patented construction, the arms 17 are completely covered with insulating covering.

The present form of the invention differs from that of the patented construction in omitting the insulating covering over the arms and making the arms 17 of malleable material, split lengthwise and terminating in loops 18, as best shown in Figs. 1 and 2 at the drawings, whereby breakable insulators 28 may be insulated in the eyes 18 and the eyesv18 compressed into the breakable insulator grooves 29 so as to hold the same in place. The insulators 28which are vpre1'- erably made of breakable material so as to be readily removable have grooves 3() for the reception of the wire S1, that is to be insulated from the arm 17. -When it is desired to electrically connect a wire with an arm 17, the insulator 28 is removed either by spreading the arms 17 and loop 18 or preferably by breaking the insulator' 28 after which the end ot the wire 20 is inserted into the eyes 18 and secured in place by any' suitable securing means 25, such as is disclosed in my patent hereinbefore referred to From the foregoing description taken in connection with the accompanying draw*- ing, it believed, the complete construe tion, operation, and advantages of the inven tion will be apparent to those skilled in the art. In conclusion it might be statedthat the device is especially adapted for use in connection with street series systems.

Vhat I claimisz-d 1. An insulator comprising an internally threaded body portion and petticoats depending therefrom, said body portion having an .external thread, a distributer sup ported on said body portion and threaded to engage said external threads, said distributer including radial arms having eye portions, insulator bodies held in said eye portions and having provisions for receiving a wire.
